If you can get it high enough, and I assume you can, why not a Delta loop
with the apex at the bottom? I have tried several different 17 meter antennas, but the Delta loop is the best I found. True, it is only bi-directional, but mine is NE/SW and works pretty well in those directions. I use a Sigma 5 vertical dipole for everything else, but the loop is better that the vertical in it's favored directions by a lot. I also used a half square on 30 meters, but have since removed it in favor of a simple inverted vee. I found the half square, while very effective on transmitting, was noisy on receive. The vee 'heard' things better and seems just as effective on transmitting. Fortunately, I was able to get the vee's apex up to 45 feet. Anything lower than that favors the half square on 30. I mention this because I also tried a half square on 17, but the loop was MUCH better. -- Jim Bob Buckeye AKA **** Jim Leder**** K8CXM since 1961 IBM retiree since 1999 http://home.fuse.net/k8cxm/ "Alan Taylor" wrote in message ... I have some space and some high trees. I already use a 400ft doublet with atu for several bands and a 30m half square and get good results. I want to improve my performance on 17m. I am now thinking about a wire antenna with reasonable performance for 17m only. I have thought about a full wave loop, even a bobtail. A broadside array would be great but I am not keen on antennas with reflectors or directors because of the complexity of support ropes. So, really some kind of antenna supported by ropes from two trees would be ideal. Any ideas please? Alan VK6BN |
